In the sea of knowledge, the sword qi is furious.

At the moment when the mystery of the second sword entered his body, Yu Yan's body trembled suddenly, and his face suddenly turned pale.

At this moment, he only felt that a terrifying sword aura was cutting his soul, and the pain of his soul being torn apart made his face become a little distorted.

"Damn, why does it hurt so much!"

Yu Yan clenched his teeth, but he was still trying his best to insist on walking, carrying the true yuan all over his body, and trying to keep the 15-zhang tall sword body behind him from being cut and broken.

Airplanes!

After three quarters of an hour, the 15-zhang tall sword body behind it suddenly emitted an invisible ripple, which carried a terrifying and fierce aura. The whole space buzzed and shook, and you felt shudder under this invisible ripple.

"What a terrifying sword intent!"

Yu Yan also secretly breathed a sigh of relief between the serious, and the emanation of this sword intent also represented that he had successfully integrated the mystery of the second sword into the sword body behind him.

Call~

Yu Gen finally exhaled a long breath, and although it only took three quarters of an hour to successfully integrate into the mystery of this sword, these three quarters of an hour were extremely painful and torturous for Yu Gen.

"Sure enough, if you want to integrate into the mysteries of these ten swords, you can't all integrate them all at once, you need to do it step by step. ”

Yu Yan muttered, his face improved slightly, "Fortunately, I was able to successfully fuse." ”

Looking at the eight purple sword qi left in front of him, Yu Yan felt a little palpitating. In his current condition, it is impossible to fuse the third path again.

However, after fusing the mystery of the second sword, the momentum emanating from the sword body behind Yu Qian was obviously much stronger than before.

The fierce and terrifying sword intent made Yu Yan feel terrified.

"Okay, first condition the true yuan for a few days, and then fuse the third way!" Yu Yan said.

With a thought, the 15-zhang tall sword body that stood behind him suddenly disappeared.

Yu Yan took a slight breath and felt the True Yuan Xuan Qi contained in his body. Obviously, his aura is even more domineering than before. The whole person exuded an invisible sword intent, which was terrifying.

When Yu Yan opened his eyes again, it was already the early morning of the second day.

A ray of sunlight shone down from above his head, and Yu Yan got up slightly and walked towards the outside of the cave.

As soon as he walked out of the cave, he was slightly stunned that there was already a white-clothed figure waiting for him at the entrance of the cave.

"Cher?!"

Yu Yan looked at the beautiful girl in white who was standing quietly at the door of his cave, and a trace of doubt flashed in his eyes.

The person standing in front of him was none other than Li Xue!

When Li Xue saw Yu Yan come out, she was startled at first, and then a charming smile appeared on her face.

"Husband, are you out of the customs?" Li Xue looked at Yu Yan and asked, a trace of excitement flashed in her eyes.

"No, just recuperate for a few days and then continue the retreat. Yu Yan said.

As he spoke, he took one step at a time, and suddenly came to Li Xue's side.

Li Xue was slightly startled, not because of Yu Qian's speed, but because of the aura emitted by Yu Gan's body that was even more powerful than before, which made her feel a chill.

"Husband, have you broken through again?" Li Xue exclaimed.

"I was lucky to fuse a trace of the mystery of the sword, so the sword intent on my body was a little stronger than before. ”

Yu Yan smiled, and then seemed to think of something, and a pair of eyes fell directly on Li Xue's body.

When Li Xue saw Yu Yan staring straight at herself, her face didn't feel slightly red, "Husband, why are you looking at me like this?"

"Cher is so pretty!"

Yu Yan smiled and quipped, "Xue'er, have you been standing here all along?"

"No, just two days ago. Li Xue said.

Two days?!

When Yu Yan heard Li Xue's words, he was slightly surprised, because when he was in the sea space, he only felt that it took one day, why did it take two days now?

Looking at Li Xue, Yu Qiandang asked, "How long have I been in retreat?"

"It's been a month. Li Xue also replied directly, not surprised. Because she knew that the monk had no concept of time between retreats, it was normal for Yu Yan not to know how long time had passed.

It's been a month?!

Yu Yan said secretly, a trace of complexity flashed in his eyes, he originally thought that it would only take him a day, but he didn't expect it to take a whole month, it seems that the mystery of fusing the sword is not as fast as he imagined!

"What's wrong with Husband?" Looking at Yu Qian's complicated face, Li Xue couldn't help but ask.

"It's okay, Xue'er, is there something wrong with you coming to me?" Yu Yan shook his head slightly, looked at Li Xue and asked.

"I want to go to the Hanging Palace to visit my mother and Xian'er, maybe I've been there in the Hanging Palace all this time. Li Xue paused, and finally spoke.

"Okay, after I have completely fused the mysteries of the remaining eight swords, I will go to the Hanging Hall to visit you and Xian'er. Yu Yan also nodded.

Li Xue couldn't help but smile happily when she saw Yu Yan agree.

"By the way, Sister Shuxiang is still in retreat, if my sister wakes up, you can bring my sister with you. Li Xue seemed to think of something, and said.

"Well, good!" Yu Yan smiled gently.

Then, under Yu Qian's eyes, Li Xue's figure flashed and disappeared in front of Yu Qian.

Watching Li Xue leave, Yu Yan calmed down slightly, then looked in a certain direction, took one step, and the whole person disappeared in front of the cave.

The next moment, when he reappeared, he was already in front of a simple wooden house.

As soon as Yu Yan appeared, he looked into the wooden house. With his current cultivation strength, he saw at a glance the beautiful woman in white sitting cross-legged on the bed.

"Xiang'er!"

Yu Yan muttered, so small that only he could hear it.

Looking at the Yu Shuxiang who was cultivating in retreat, Yu Jian couldn't help but feel a sudden pain in his heart, Yu Shuxiang had already retreated before him before he retreated.

And he naturally knew that the reason why Yu Shuxiang cultivated so hard was completely to improve his cultivation strength and not to hold him back.

Although Yu Shuxiang has never said it, as a husband and wife, how can she not know what she is thinking.

Seeing that Yu Shuxiang was still practicing, Yu Yan didn't bother, smiled slightly, and then his figure flashed, and he disappeared in front of the wooden house.

In front of a garden, surrounded by a few simple wooden houses.

There was a slight fluctuation in the space, and Yu Yan's figure once again appeared from nothingness.

"Also ......"

But seeing the quiet environment around him, Yu Yan couldn't help but be slightly stunned.

Soon, he saw the two wooden houses side by side, and two young men in white were sitting cross-legged in the wooden houses.

"It seems that everyone is preparing to enter the retreat!"

Yu Yan looked at the demon moon and Yang Feng in the wooden house and couldn't help but sigh. I haven't seen Ouyang Bai yet, because Ouyang Bai has already gone to cultivate from the Holy City Zhao Tian.

"Everyone else is cultivating, you kid poured out!"

Just as he was about to leave, a familiar voice came into his ears.
